- Abstract: Objective: We conducted a two-way crossover trial to investigate the effects of a personal air-conditioning system on fatigue induced by mental load. Design: Sixteen healthy volunteers performed mental fatigue-inducing tasks that consisted of a 2-back task for 30 min and the A, B, and C tasks of the advanced trail making test (ATMT) for 30 min on four occasions (4-hour mental load) with or without the personal air-conditioning system with a 1-week interval. We evaluated work performance by mean reaction time, number of errors, total trial number, and reaction time from the previous task to the next task in the ATMT and subjective fatigue sensation by the visual analogue scale (VAS). Results: The mean reaction time, the number of errors, and reaction time from the previous task to the next task were significantly lower, and the total trial number was significantly higher when the personal air-conditioning system was used. On the other hand, the personal air-conditioning system did not affect fatigue sensation in VAS. Conclusion: We found that the personal air-conditioning system attenuated mental fatigue and increased the subjects’ motivation.
